Previous GeneCards Identifiers for RRAGB Gene
Ras-homologous GTPases constitute a large family of signal transducers that alternate between an activated, GTP-binding state and an inactivated, GDP-binding state. These proteins represent cellular switches that are operated by GTP-exchange factors and factors that stimulate their intrinsic GTPase activity. All GTPases of the Ras superfamily have in common the presence of six conserved motifs involved in GTP/GDP binding, three of which are phosphate-/magnesium-binding sites (PM1-PM3) and three of which are guanine nucleotide-binding sites (G1-G3). Transcript variants encoding distinct isoforms have been identified. [provided by RefSeq, Jul 2008]
GeneCards Summary for RRAGB Gene
RRAGB (Ras Related GTP Binding B) is a Protein Coding gene. Diseases associated with RRAGB include parasitic helminthiasis infectious disease. Among its related pathways are Gene Expression and Signaling by GPCR. GO annotations related to this gene include GTP binding and guanyl ribonucleotide binding. An important paralog of this gene is RRAGA.
UniProtKB/Swiss-Prot for RRAGB Gene
Guanine nucleotide-binding protein that plays a crucial role in the cellular response to amino acid availability through regulation of the mTORC1 signaling cascade. Forms heterodimeric Rag complexes with RRAGC or RRAGD and cycles between an inactive GDP-bound and an active GTP-bound form. In its active form participates to the relocalization of mTORC1 to the lysosomes and its subsequent activation by the GTPase RHEB. Involved in the RCC1/Ran-GTPase pathway.
